Lightheaded and dizzy on period: Causes and treatments – Medical News Today

Feeling dizzy on a period is not a typical menstrual cycle symptom. This dizziness may indicate an underlying issue, such as anemia or heavy bleeding.
Sometimes, the dizziness that a person experiences has no connection to their period, and the timing is merely coincidental.
However, anyone who experiences extreme dizziness that does not go away with at-home treatment should see a doctor.
In this article, we examine the causes of dizziness that may be related to a period. We also look at the treatment options and when a person should see a doctor.
Dizziness is a common symptom that affects about 5% of the population each year. However, dizziness is not a typical period symptom.
Feeling dizzy during a period is not necessarily a cause for concern. However, a person may need to talk to a doctor to determine why they are experiencing this symptom.
There are numerous possible causes of lightheadedness, some of which may relate to menstruation:
Some people who experience menstrual cramps may avoid eating or drinking during their period, fearing that it will worsen their stomach pain. As a result, they may have thirst- or hunger-related dizziness.
Period-related hormonal fluctuations may also change the body’s fluid balance. For some people, this may affect how much they need to drink.
Heavy menstrual bleeding, also known as menorrhagia, can cause a person to become anemic. Anemia occurs when red blood cells cannot carry enough oxygen throughout the body. People who are already anemic may find that their condition worsens during their period, especially without treatment.
Although there are many types of anemia, iron-deficiency anemia is the most common form.
Heavy bleeding can also cause a person to feel dizzy. If a person feels lightheaded and has significantly more blood loss than usual, they should immediately get help from a healthcare professional.
Premenstrual dysphoric disorder (PMDD) is a severe type of premenstrual syndrome (PMS). It causes a wide range of symptoms before — and sometimes during — a period, which may include dizziness.
Some other symptoms of PMDD include:

A doctor may recommend brain imaging tests if they suspect a neurological problem.
The treatment for dizziness will depend on the cause. Some options that a doctor might suggest include:
Some strategies that a person can use to manage dizziness at home include:
A person should also monitor their bleeding. Doctors consider bleeding heavy if it soaks through one or more pads or tampons each hour for a few hours in a row.
Heavy bleeding alongside dizziness may be a medical emergency.
Dizziness is not usually an emergency unless a person has other symptoms, such as:
Anyone who experiences these symptoms will need to go to the emergency room.
An episode of dizziness might not be a serious problem if it gets better with rest or eating.
If a person regularly experiences dizziness during their period, or the dizziness does not get better after a period, it is important to get advice from a doctor.
People undergoing treatment for period-related dizziness should see a doctor if:
Dizziness may increase a person’s risk of injury, as they may stumble or pass out. However, dizziness during a period does not usually signal a serious or life threatening medical condition.
Many factors may cause dizziness during a period, such as:
The cause may also be unrelated to menstruation.
Depending on the cause, several treatments are available to control lightheadedness during a period.
If a person is worried about their dizzy episodes or is losing a significant amount of blood, they should seek help from a healthcare professional as soon as possible.
